Let's divide 160661 by 2
We want to divide 160661 by 2.

On to step 1:
The number 2 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 2

Advancing to step 2:
The number 2 fits into 16 8 times, leaving a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 16 from 16 to get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 2

Step 3:
0 divided by 2 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 80.0
The remainder is 0 after subtracting 0 from 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 2

On to step 4:
2 goes into 6 3 times with a remainder of 0.
The next digit of our result is 3. 
Result so far: 803.0
If we take 6 away from 6, we end up with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 2

Moving on to step 5:
2 can be fit into 6 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 8033.0
Subtract 6 from 6 to get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 2

Step 6:
2 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 80330.0
Subtract 0 from 1 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
2 goes into 10 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 80330.5
Deduct 10 from 10 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 80330.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
0 divided by 2 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 80330.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 80330.5, with a leftover of 0.0.
